Code 128 Stitch Enable
ThisparameterdetermineswhetherCode128tagstitchingisenabledordisabled.

Scans Required
ThisparametersetsthenumberofscansrequiredtoreadaCode128barcode.
Increasingthenumberofscanscanimprovereadingnominalbarcodes.Thereare
foursettings:1scan,2scans,3scans,and4scans.Thedefaultis1scan.Setthis
